Document Summary
Is from touch haptic perception is the process of actively feel/explore objects using your hands for recognizing/ identifying of object, surface and their properties . This is useful in darkness e. g. feel for light switch. Haptic perception is different compared to just other somatosensory perception (just touch) is for this perception you need active exploration in order to get clearer perception. Haptic perception ( meaning you actively explore) is better because we use muscles actively and this gets at more info via efference copy ( info about what we re doing w/ our muscles). The efference copy also allows additional info about where is actually the fingers in space thus, allows for integration of where your hands are at different times in space. Perform certain type of action (usually from hands) to gather information about certain type of (haptic) features of objects. These actions involve using hands with different strategies/actions (stereotypical) to measure different features (e. g. weight vs. texture).
